Plumbing replacement and installation is a critical service for maintaining the safety, comfort, and functionality of your home, especially in a city like San Diego where many properties were built decades ago and still rely on outdated plumbing systems. Whether you’re dealing with leaking plumbing pipes or fixtures, clogged or slow drain, low water pressure, or planning a home remodel, professional plumbing replacement ensures that your water supply and drainage systems are efficient, leak-free, and up to current building codes.
In this article, we’ll explore when and why you might need plumbing replacement or new installations, what the process involves, and what costs to expect.

Common Customer Plumbing Issues in San Diego
San Diego’s diverse housing stock and aging infrastructure present unique plumbing challenges. Below are some of the most common plumbing issues that homeowners in the county face:
- Сlogged Toilet & Sink. Clogged toilets and sinks are one of the most frequent plumbing issues for San Diego homeowners. They are often caused by accumulated debris or inappropriate items being flushed down the drain. If left untreated, these blockages can lead to slow drainage, unpleasant odors, and even water damage.
- Roots in the Drain. Tree and shrub roots often invade underground pipes in search of moisture, particularly in older San Diego homes with aging sewer lines. Over time, these roots can create serious blockages, damage pipe walls, and cause sewage backups.
- Aging Plumbing Systems. Many San Diego homes, especially those built before 1970, have copper and galvanized pipes. Over time, these materials corrode, which can lead to restricted water flow, leaks, and even pipe failure.
- Low Water Pressure. Decreasing water pressure is a frequent complaint. In older homes, this often signals hidden leaks that require replacement rather than repair.
- Discolored or Rusty Water. Brown or yellow-tinted water usually indicates rust inside aging pipes. This affects water quality and may indicate that the pipes are close to failing.
- Slab Leaks. Homes built on concrete slabs are susceptible to hidden leaks underneath the foundation. These leaks are difficult to detect and often require rerouting or replacing sections of pipe.
- Hard Water Damage. San Diego has notoriously hard water, which leaves mineral deposits in pipes and appliances. Over time, these deposits can reduce efficiency and damage plumbing fixtures, often requiring replacement.
- High Water Pressure. Excessive water pressure can strain pipes, fixtures, and appliances, causing leaks, bursts, and premature wear. In San Diego, a common solution is to install a pressure reduction valve to maintain safe levels and protect the plumbing system. For added protection, consider pairing it with a Moen water leak shut-off valve.
- Remodeling & Home/ADU Additions. Plumbing upgrades are often necessary during kitchen and bathroom remodels or room additions. Older systems often cannot support new fixtures or layouts without updates.
- Outdated or Failing Fixtures. Leaky toilets, dripping faucets, and inefficient water heaters are signs that it’s time to replace them rather than repair them. Newer, water-saving models can reduce utility bills and improve performance.
- Code Compliance & Earthquake Safety. California has strict plumbing codes, and San Diego homes must meet seismic safety standards. Replacing old plumbing ensures that your system is code-compliant and earthquake-ready.
Proactively addressing these issues with professional plumbing replacement and installation helps avoid costly damage and improves your home’s long-term value.

Common Pipe Materials We Work With
Choosing the optimal materials for your plumbing replacement or installation is essential for ensuring long-term durability, efficiency, and compliance with local codes.
At Almco, we use only high-quality, approved materials that meet San Diego’s building standards and are suited to your home’s conditions:
- PEX. Flexible, easy to install, and resistant to scale and chlorine. Ideal for repiping older homes with minimal wall damage.
- Copper. Time-tested material which is preferred in many San Diego homes for its relatively long lifespan (about 7–10 years) and ability to ensure water purity.
Every plumbing system—whether a supply line, drain system, or gas line—requires the correct material for safety and longevity. Our technicians evaluate:
- Water pressure and flow requirements
- Exposure to temperature fluctuations
- Structural access (slab, crawl space, or walls)
- Potential for seismic movement
We also ensure that all connections, valves, and joints are properly installed and pressure-tested to prevent leaks or failures. Almco’s team follows California Plumbing Code requirements for all jobs.
